Vyasan Edavanakad has written the story for Metro, which is an edge-of-the-seat thriller set in Kochi. It deals with three parallel stories of a cop, a group of youngsters out on a fun trip and a gangster, who controls Kochi. Sarath Kumar plays an upright cop, who stands up for the common man. He neither has romantic interest, nor delivers punch dialogues like in his Tamil films.
Metro is a limited budget movie and it has been produced by Dileep's Graand Productions. Rima Kallinghal has played the female lead. Suresh Krishna, Nishant Sagar, Bhavana, Suraj, Nivin Poly, Bhagath, Jagathy and Shammy Thilakan are in other cast.
